Nokia N-Gage QD

N- Gage QD Prototype

I recently came into a n-gage that will only play games. The phone and messaging functions are all in the menus but seem to have been disabled. Anyone know if it is possible to enable these functions on the device.

Take it to a T-Mobile company store. Not to the guy in the mall. Check the T-Mobile website for the closest location, or call T-Mobile customer service they should be able to help you use your phone as a phone or tell you were the nearest T-Mobile company store is in your area.
